The heat insulators 12 and 42 may use glass wool, rock wool, ceramic wool, or the like, in which heat insulation performance is exhibited even at high or low temperatures, or may be different one by one. This three-layer insulation structure provides superior insulation performance compared to the case of using insulation materials of the same thickness in a single layer, so as to protect the CCTV camera 60 and the internal devices from the environment in the temperature range of -50 to +200 ℃. do.

The reduction gear motor 21 of the left and right angle control unit 20 is firmly installed in the lower housing 10 by an appropriate fixing device (not shown), and the rotary pipe 23 also has a suitable sealing device and bearing ( It is rotatable using a lamp, etc.), but it is not installed in Shanghai and is installed to seal the inside. Since the installation structure of the reduction gear motor 21 and the rotary pipe 23 is obvious to those skilled in the art, detailed description thereof will be omitted.

The driven gear 22 of the left and right angle adjusting unit 20 may be directly connected to the rotary pipe 23 to rotate the rotary pipe 23, but as shown in FIGS. 2 and 3, the driven gear 22 and the driven gear 22 may be rotated. The rotational force may be transmitted between the rotating pipes 23 via the friction clutch 24.

The friction clutch 24 is a sliding pipe 24a which is in sliding contact with the lower surface of the driven gear 22, and a rotating pipe extending downward through a central through hole of the driven gear 22 and the sliding disk 24a. It consists of a fixed disk 24b fixed to the lower end of 23, and a compression spring 24c provided between the sliding disk 24a and the fixed disk 24b.

The sliding disc 24a is always elastically in close contact with the lower surface of the driven gear 22 by the elasticity of the compression spring 24c.

In FIG. 3, reference numeral 22a denotes a snap ring for preventing the driven gear 22 from moving upward due to the elasticity of the compression spring 24c.

The lower end of the inner space of the rotary pipe 23 is filled with a sealing member 23a for sealing.

Therefore, the left and right angle control unit 20 acts as follows.

When + power is applied to the reduction gear motor 21, the drive gear 21a rotates clockwise and the driven gear 22 rotates counterclockwise. The driven gear 22 transmits the rotational force in the same direction to the sliding disc 24a of the friction clutch 24, and the sliding disc 24a is connected to the rotating pipe 23 through the compression spring 24c and the fixed disc 24b. The rotational force is transmitted in the same direction to cause the rotation pipe 23 to rotate counterclockwise. Therefore, the upper housing mounting stand 30 and the upper housing 40 installed on the upper end of the rotary pipe 23 is rotated to the right.

When the upper housing 40 is rotated to the left, when-power is applied to the reduction gear motor 21, the rotary pipe 23 rotates clockwise to follow the same procedure to rotate the upper housing 40 to the left.

The friction clutch 24 causes slippage between the sliding disc 24a of the friction clutch 24 and the driven gear 22 when the upper housing 40 and the upper housing mounting stand 30 are manually rotated from the outside. The drive gear 21a of the driven gear 22 and the reduction gear motor 21 is prevented from rotating to protect the reduction gear motor 21.

The upper housing mounting stand 30 is connected to the connecting disc 31 fixed to the upper end of the rotary pipe 23, and vertically connected to the left and right sides of the connecting disc 31, respectively, connecting rods of the vertical angle adjustment unit 70 ( It consists of the support stand 32 in which the connecting rod installation hole 32a in which the left or right end of 73 is inserted and fixed is formed.

The connecting rod 73 of the vertical angle adjusting unit 70 is firmly fixed to the connecting rod installation hole 32a of the left and right supports 32 so that the connecting rod 73 does not rotate.

However, the connection between the rod 73 and the upper housing 40, using a suitable sealing device and a bearing (not shown), such as relative rotation is possible, but the left and right relative movement is to be sealed inside.

A plurality of viewing windows 50 installed in the see-through space 43 of the upper housing 40 are made of heat-resistant glass that can withstand heat, and the foremost viewing window 50 is made of double heat-resistant glass, each of which is heated The 51 is incorporated to prevent the occurrence of frost caused by the temperature difference between the inside and the outside of the upper housing 40.

The drive gear 71a and the driven gear 72 of the reduction gear motor 71 of the upper angle adjusting unit 70 are bevel gears so as to transmit rotational force in a right angle direction.

The reduction gear motor 71 of the vertical angle adjustment unit 70 is firmly installed by an appropriate fixing device (not shown) inside the upper housing 40.

Although the driven gear 72 may be directly connected to the connecting rod 73 to rotate the connecting rod 73, the friction clutch 74 between the driven gear 72 and the connecting rod 73 as shown in FIGS. 5 and 6. The rotational force can be transmitted through).

The friction clutch 74 is fixed to a sliding disc 74a in sliding contact with one side of the driven gear 72, and a connecting rod 73 passing through the center through hole of the driven gear 72 and the sliding disc 74a. Fixed disk 74b and a compression spring 74c provided between the sliding disk 74a and the fixed disk 74b.

The sliding disc 74a is always elastically in close contact with one side of the driven gear 72 by the elasticity of the compression spring 74c.

In Fig. 6, reference numeral 72a denotes a snap ring for preventing the driven gear 72 from moving to the left due to the elasticity of the compression spring 74c.

Therefore, the vertical angle adjustment unit 70 acts as follows.

When + power is applied to the reduction gear motor 71, the drive gear 71a rotates clockwise and the driven gear 72 rotates clockwise. The driven gear 72 transmits the rotational force in the same direction to the sliding disc 74a of the friction clutch 74, and the sliding disc 74a is equal to the connecting rod 73 through the compression spring 74c and the fixed disc 74b. It transmits rotational force in the direction. However, since the connecting rod 73 is fixed to the upper housing mount 30 so as not to actually rotate, the upper housing 40 in which the reduction gear motor 71 is installed is rotated downward.

When the upper housing 40 is rotated upward, when-power is applied to the reduction gear motor 71, the upper housing 40 is rotated upward by the same procedure.

The friction clutch 74 causes a slip between the sliding disc 74a of the friction clutch 74 and the driven gear 72 when the upper housing 40 is manually rotated upward or downward from the outside so that the driven gear ( 72) and the drive gear 71a of the reduction gear motor 71 does not rotate to protect the reduction gear motor 71.

The power cable 80 is connected to the inner space of the lower housing 10 so that some electric wires are connected to the reduction gear motor 21, and the rest of the power cable 80 exits the lower housing 10 through the inside of the rotating pipe 23 and the upper housing. Enter 40.

And the friction clutches 24 and 74 are respectively configured in the left and right angle control unit 20 and the vertical angle control unit 70, by applying an external force to the upper housing 40 and the upper housing mounting stand 30 from the outside. Thus, the upper housing 40 can be turned left or right or up and down without damaging the reduction gear motors 21 and 71.

The CCTV camera of the present invention is composed of the left and right angle control unit 20 and the vertical angle control unit 70, so that the perspective direction of the camera can be remotely controlled even during the test of the specimen in the environmental reproduction test facility.

In addition, since the hot wire 51 is formed in the front viewing window 50 of the upper housing 40, defrost does not occur in the viewing window 50 due to an internal and external temperature difference.

As described above, the CCTV camera of the present invention can withstand the temperature range of -50 ~ +200 ℃, it does not need any additional facilities to circulate water or air, the structure is simple, the manufacturing cost is low, and maintenance It is easy to use, and there is no fear of lethal damage to the built-in camera due to instantaneous breakdown or malfunction during use, and it is possible to freely monitor the desired part of the space within the environmental reproduction test facility, and it does not cause eroticism on the viewing window.
